2012 ThemeFertility 2.0 - Black Rock City is a kind of Petri dish. Theme camps cling in fertile clusters to its latticework of streets, artworks tumble out of it, like pollen on the air. These nodes of interaction mutate, grow and reproduce their kind. Burning Man communities have now escaped this capsule world: our culture in a Petri dish has effloresced - it spreads across five continents. This year's art theme contemplates the tendency of any being or living system to create abundant life.
